The sash 4 includes a sash upper frame, a sash horizontal frame that is a sash lower frame, and a sash vertical frame that is a left frame and a right frame that form a frame surface along each of four sides of the opening. It is composed of a sash main body and a sash mounting piece 4d (see FIG. 3) provided around the sash main body and fixed to the skeleton side.

After the sash 4 is fixed to the periphery of the opening in this manner, a plurality of base materials 8 are provided outside the frame.
The outer wall material (siding material) 7 is attached to the outside of the base material 8 and the outer wall construction is completed.

る。In order to keep the inside of the building thermally insulated from the outside and keep the indoor air-conditioning conditions (temperature and humidity) optimal, a heat insulating material is often provided between the frame and the outer wall material (siding material). . In such a residential building, the heat insulating material does not absorb moisture, prevents dew condensation due to the temperature difference between the inside and outside of the room, and also improves the drainage performance to prevent the deterioration of the heat insulating material and wood. In recent years, a housing structure by a ventilation method in which a ventilation space 5 is provided between the outer wall material and air is circulated has been used.

れていた。[0005] The sash forming the window frame of such a building needs to seal its peripheral portion in order to maintain airtightness and watertightness with the outer wall material. FIG. 3 shows an upper frame portion of a conventional sash mounting structure. In the conventional sash mounting structure, when the sash 4 and the outer wall member 7 are mounted on site, a backup material 19 (in FIG. 3, a metal section having a substantially hook-shaped cross section is provided in a gap between the outer wall member 7 and the sash 4). Sealing work using the long member and the irregular-shaped sealing material 18 was performed.

That is, a special contractor is required for the sealing work, and the skill of the builder is required. Further, there is a concern that water leakage due to deterioration of the sealing material may occur in the long term. If water leaks from the upper outer wall surface of the sash, for example, the water that has entered the ventilation space between the frame such as the pillar 6 and the outer wall material 7 accumulates in the upper portion of the upper sash frame 4a (FIG. 3). Water 20), and enter the room from the location.

Deterioration of the building body 6, the outer wall material 7 and the like is promoted, and a problem such as water leakage into the room is caused. On the other hand, the above problem does not occur unless sealing work is performed between the sash and the outer wall material, but water leaks in the ventilation space between the skeleton 6 and the outer wall material 7.

On the other hand, if the sealing work is not performed between the sash and the outer wall material on the foundation of the building outer wall, the above-described problem does not occur, but it is not possible to prevent rainwater from being blown from the location.

At the lower end portion, a drainer 23 having a substantially hook-shaped cross section is fixed to the frame 22 so as to cover the lower end of the outer wall member 7. That is, the drainer 23
Is the same position as the sash upper frame 4a in FIGS. 1 and 2,
It is arranged as a shape and performs a similar function. Therefore, the same waterproof effect can be obtained also in the waterproof structure on the base of the building outer wall shown in FIG.

In this configuration, a cover material having a size substantially covering the ventilation hole is provided at a position away from the ventilation hole by a predetermined distance. With such a configuration, water that has entered the ventilation space can be easily discharged, and
Almost all rainwater from below can be prevented.

い。According to the present invention, the water that has entered the ventilation space can be easily discharged, and the rainwater blown between the upper frame and the outer wall material can be almost prevented, so that the advantages of the ventilation method can be utilized.
Similar effects can be obtained on the foundation of the building outer wall. In addition, by arranging a flexible member having a check valve function,
Rainwater blown between the upper frame and the outer wall material, or rainwater blown between the outer wall material and the base on the foundation of the building outer wall,
It can be prevented more reliably and the function of discharging water is not hindered.
